After thedraw-rods and aws have been adjusted into clamping position with thedesired tension, as shown at the right of Fig. 2, the jaws 30 and 31will be held againstI spreading apart by a locking dog 46 pivoted on apin 47, said dog 46 being frictionally held against the side wall oi'"the central recess 23. The dog 46has a depending tooth 47a for engagingthe apertures 44 of the wheel 42. The adjusting wheel 42 is nonrotatablyheld upon the inner end of the draw-bar 36, as by a key 48, as mostclearly shown in Fig. 4.

In order toprovide an additional support for the rail on curves, a railbrace strip 49 is provided, said strip having an inclined section 50 forengaging the top of the rail and being secured to the guard plate 19, asby rivets 51, as clearly shown in Fig. 2.

In operation, the safety guards 19 will first be laid within the sidechannels 17 and 18. The rails 21 and 22 will then be placed within saidguards, as shown at the left of Fig. 2. The apron cover 24 will then beremoved, whereupon the operator will rotate ythe adjusting wheels 42, bymeans ot the tool 45, in such directions as to causethe draw-rods 36 topull each pair of jaw members 30 and 31 from the position shown at theleft of Fig. 2 to the position shown at the right of said figure. Thelocking dogs 46 will then be manually forced down into one of theapertures 44 for preventing the adjusting wheel 42 from loosening. Itwill be understood that when the rails are to be removed from the tie,the operation will be the reverse of that just described, and that thelocking dogs 46 will be held in raised position by reason of theirfrictional contact `Withthe side walls of the central channel.

While there has been disclosed in this specification one form in whichthe invention may be embodied, it is to be understood that this form isshown for the purpose of illustration only, and that the invention isnot to be limited to the specific disclosure but may be modilied andelnbodied in various other forms without departing from its spirit. Inshort, t-he invention includes all the modifications and embodimentscoming within the scope of the following claims.

Having thus fully described the invention, whatis claimed as new, andfor which it Yis desired to secure Letters Patent, is:

1. In a railroad cross-tie, a hollow casino having a transverse channel,and a U-shaped wear strip seated in said channel for receivlng a rail,said wear strip having outwardlyextending flanges to fit over the top ofthe cross-tie.

2. In a railroad cross-tie, a hollow casing' having a pair of transversechannels, and a pair of U-shaped wear strips seated in said channels forsupporting a pair of rails, each of said wear strips havingoutwardly-extend ing flanges to tit over the top of the cross-tie.

3. In a railroad cross-tie, a hollow casing having a transverse channelfor supporting a rail, a second transverse. channel. and meansladjustable from said second transverse channel for clamping said railwithin said cha nnel.

4. In a railroad cross-tie, a casing having a transverse channel Vforsupporting a rail, a second transverse channel, and meansI ad justablefrom said second transverse channel for clamping said rail within saidchannel.

5. In a railroad cross-tie, a hollow casing having a pair ot transversechannels for supporting a pair of rails respectively, a third transversechannel between said rails, and means operable from said thirdtransverse channel for clamping said rails within said rail channels.

6. In a railroad cross-tie, a hollow casin Y having a pair oit'transverse channels locate( near the ends of said tie for supporting apair of rails respectively, a third transverse channel between saidrails, and means operable from said third transverse channel forclamping said rails within said rail channels.

7. In a railroad cross-tie, a hollow casing having a pair of transverseend channels for supporting a pair of rails respectively, a centraltransverse channel located between said side channels, and meansoperable from within said central channel for clamping said rails withinsaid side channels.

8. In a railroad cross-tie, a hollow casing having a pair of transverseend channels for supporting a pair of rails respectively, a centraltransverse channel located between said side channels. and meansoperable from within said central channel for adjustably clamping saidrails within said side channels.

9. In a railroad cross-tie, a hollow casing having a transverse channel.for receiving a rail, a pair of slidable rail clamps for engagingopposite sides of said rail, and means located within said casing forengaging said rail clamps and Jforcing them against said rail.

10. In a railroad cross-tie. a hollow casing having a transverse channelfor receiving a rail, a pair of slidable rail clamps for engagx ingopposite sides of said rail, a rod having threaded engagement with bothof said rail clamps, the portions of said rod where it engages saidclamps being of diiilerent diameters and of opposite pitch.

11. In a railroad cross-tie, a hollow casing having a transverse channelfor receiving a rail, a pair of slidable rail clamps for engagingopposite sides of said rail, a rod having threaded engagement with bothof said rail llll lill) lll clampm the portions of Said rod Whore itengages said clamps being ol? difli'oront diamoliora and ol oppositepitch, and a rotary ad jnsing Wheel on tlio ond of said rod.

In a railroad @roos-tio, a hollow casing liavingl a transverse channel:for receiving a rail, a pair ol slidablo rail clamp# for engaging;opposite aides ol" said rail, a rod having; tliroadod ongagon'lonlv withbolli of said rail clamps, the portions of said rod where it onengagesSaid clamps being of different di.- aniotors and oi" opposite pitcln arotary adjiistingg Wheel on tlio end of said rod, and lnoanal :forlocking' said adjusting wheel in an)7 dosirod position.

13. lo a railroad orosatie, a hollow @airing having` a pair oiltransverse sido Channels for rocoiving; and supporting a pair of railsrenpootivoly, a Libarmvorao Uontral channel lo fatod liomvoon said sidooliaimols, oacli of Said, oido oliannols having a pair ol .alidalilorail clamps projooting liliorotllrougli, rods Within said casing', andmoans on said roda for movingr1 .amid rail clamps in oppositedirections; to clamp said railfs.

14. In a railroad oroaalio, a hollow casing having a li-ransvoraoChannel, a` wear strip seated in said ol'mnnol lor l'ooeviiig a rail,and a liraoo airp .ff-,ocurod to the ontor edge olf said wear Strip forproviding an additional support 'for said rail on ourvoa.

In oatiinony whereof, I havo aillixod my Signature lo thiaspeoilioalioo.
